numpy.polynomial.polynomial.polydiv

numpy.polynomial.polynomial.polydiv(c1, c2) [source]

Divide one polynomial by another.

Returns the quotient-with-remainder of two polynomials c1 / c2. The arguments are sequences of coefficients, from lowest order term to highest, e.g., [1,2,3] represents 1 + 2*x + 3*x**2.

Parameters:	c1, c2 : array_like 1-D arrays of polynomial coefficients ordered from low to high.
Returns:	[quo, rem] : ndarrays Of coefficient series representing the quotient and remainder.

>>> from numpy.polynomial import polynomial as P
>>> c1 = (1,2,3)
>>> c2 = (3,2,1)
>>> P.polydiv(c1,c2)
(array([ 3.]), array([-8., -4.]))
>>> P.polydiv(c2,c1)
(array([ 0.33333333]), array([ 2.66666667,  1.33333333]))
